Great experience at LFPN. From touchdown till walking under the Eiffel Tower it took us about 1h10min.
The fuel truck arrived while disembarking, we were refuelled 10mins after landing.
Getting out of the airport is easy, just make sure you get an Entry Card before walking out the door. You can use it to open the door instead of using the green button, making sure it actually works. Uber is the way to go, easy and reasonably priced.
Coming back we had no issues, the card opened the door, that was it. No one there to collect any fees.
No problems with ATC, got the clearance with Ground after the runup, Orly Delivery couldn´t be reached by radio. Paris Control was pretty busy, make sure to isolate your passengers and know your game.
